Easy Fudgy Chocolate Brownies

Dense, fudgy brownies made with melted butter and unsweetened chocolate, mixed with eggs and minimal flour for an intensely chocolatey treat. Rich and chewy with optional nuts for texture, these are perfect for potlucks, bake sales, or simple weeknight desserts. This straightforward method uses microwave-melted chocolate to streamline prep without sacrificing depth of flavor.

Tips
Microwave chocolate in short increments to prevent seizing; gentle heat preserves flavor and texture.
Don't overbake; brownies continue cooking as they cool, so pull them from the oven when edges are set but center slightly jiggles.
Cool completely before cutting for cleaner slices and better fudgy structure.
Good to Know
Airtight container at room temperature up to 5 days, or wrapped and frozen up to 2 months.

FAQ
Can I use dark chocolate instead of unsweetened?
Yes, but reduce sugar by 1/4 cup since dark chocolate contains added sugar. Start tasting your batter to adjust sweetness to preference.
How long do brownies keep in an airtight container?
Up to 5 days at room temperature. For longer storage, wrap tightly and freeze up to 2 months. Thaw at room temperature for 1-2 hours.
Can I double this recipe?
Yes, double all ingredients and use a 9 x 13-inch pan. Increase baking time to 45-50 minutes, checking doneness around 45 minutes.
